Sewer Testing Scheduled To Take Place In New Canaan

Information via the town of New Canaan

NEW CANAAN, CT — New Canaan, in conjunction with AECOM, has contracted Flow Assessment Services to conduct dye testing in 23 locations throughout the sewered portion of the town.

According to a news release provided by the town, the testing is completed by adding a non-toxic green or red tracer dye to the town’s stormwater system at each of the proposed locations. The adjacent sewer system is inspected for the duration of the testing to verify if the dyed water is infiltrating from the stormwater system.

The dyed water testing will help the town identify inflow/infiltration into their sewer system by identifying direct or indirect connections from their stormwater system. The tests will last approximately 2-3 hours in each location, according to town officials.

Work is currently scheduled to take place Feb. 21 to March 1. Weather, holidays and weekends may shift test periods beyond the 24 to 72 hour time frame, town officials said.

Public safety officials will be notified prior to the testing beginning.

The tracer dye poses no threat to human health or the environment, however dyed water may possibly be seen discharging from stormwater outfalls as a result of testing. This is normal and should not be cause for alarm, according to town officials.

Anyone with questions or concerns can contact Flow Assessment Services at 1-888-311-9799.
